Chapter 5 Metrics Data Analysis in Frequency Domain

Frequency Distribution: An Analysis Tool

All processes show variations that will become evident if a frequency distribution is drawn on the process metric. Understanding process variation, Demming observes, will lead to profound knowledge of the process. Frequency distribution also contains an indication about probability of occurrence of events. Analysis of metrics data in the frequency domain would result in empirical distribution curves. The shape and structure of these distribution curves represent a process signature. Analyses of distributions are usually based on several well-known probability distributions. We have selected two distribution types that find practical views in software ...
